Application filed April 12,1923. Seria1 No.-631',568.

My invention relates'to new and useful improvements in motor mountings and; the

dynamos :and the like and in which the vibration of the mounting and parts associated therewith-is reduced toa minimum, thereby eliminating objectionable noisesand enabling me to utilize the mounting for supporting motors used in connection with playerpianos,- refrigerating machines and other household appliances or] for supportingeleo' tric generators on cartrucks. v

Further ObJBC-tS ofthe invention are to provide a mounting fora motor ;or dynamo;

which successfully absorbsall the vibration the motor or dynamo from its support there by preventing accidental, grounding of the electriccircuits.

With these and other objects in view my hereinafter more fullyz -;described and claimed, and illustrated in the accompanying drawings, infwhicha Figure lis an end elevationishowingthe ftric motorn- Figure2 is a side elevation of the same.

V Figure 6 is ;a fragmental detailwview showing'the means for connecting theother endof the spring to the; stationary'sup- -0It. p 7 is anend elevational view ofja cross section taken ed for supporting a dynamoin positionon a car truck. Y v i r i Referring by numerals to the accompanying drawings, lOrindicates a platform to which are fixed the lower'ends 11 of' sta-,

tionary supports 12 which are spaced from each other a suitable distance to" I accommodate'a motor M. Stationary supports 12 are arranged in pairs and the upper ends of each'pair are united by a curved portion-14E and seated in said-portions and spaced a suitable distance upwardlyfrom motor M are.

the ends-of a rod 15 These ends arepreferably threaded andreceivelnuts 16 which are deslgned to lock saidrod in position on said supports.

' A I sleeve 17, formed i of I material and; preferably of resilient; nature isj-arr'angedon rod ,15 between supports 12. A

pair of suspensionmembers18..is=arranged between supports 12 and'each member is provided; at its upper end, with a loop portion 19which engages sleeve 17 and swingngly supports said member in position, A short'distance below rod 15 the legs of members 18. divergeoutwardly as indicated at 20 andthen'curve ,downwardlyvas at: 21 so I that'the straight vertically disposedportions produced bythe same and whichinsulates positions aseindicat'ed at-Ql and form supports to which is fixed the'base of motor M.

Thus the" motor M is supported in position by members 18'whichvar'e suspended from rod 15 carried by thestationarysupports 12' y and the motor willha ve" the tendency to e occupy acentral position relative to supv ports 12. I One end proper tension I" employ a coiled spring 27,

means of athreaded ro'df28 anda butterfly i nut29 toone of the members 18 and the'opposite end of {said spring "is anchored vto an insulator 30 which insulatoris-connected by a link 31 to 0. Qffthe supports 12. 7 'Byturnpulley-25 oflmotor M. i

Inj'order to 'prefvent'twisting of motor M due to the tension ofthe belt and the'spring applied to one end'thereof, I providea small spring 32 which isjoppositely disposed relative to spring 27 and partiallyIcounteracts of the shaft ofmotor I [a pulley 25 overwhich operates a belt 26 and in order to maintain this beltunder one end of which is adjustablyfixed by V said sp'ringand balances the'motor. This spring is connected at onependfto threaded rod 34: which is adjustablyheld in position on member 18 by means of aabutterfly nut which form acne-point support for the '10s" 35 and'the opposite end of. said springis connected to the'stationary member 12in the motor and the motor isyieldingly held its pro-per operative position by meansof springs 27 and 32.' Sleeve 17 beingmade of insulation material and the ends. of the springs being connected to the stationary supports '12 by means of insulators 30, the

motor is completely'insulated from supports 12 and platform and all danger-oigrounding or shortcircuitingoi the motor 18 there byYeliminated. The divergent portions are resilient. and the diameter'of rod 15 is such as to providea resilient support and sleeve 17 is preferably made of resilient or yielding material whereby all vibration produced bythe running motor-is absorbed by members 18 and sleeve '17 and rod 15, thus providing a quiet driving means which is especially adaptedfor use in homes. I

' In the form'illustratedfin Figure 7 the rod 15 issupported in loops 36 formed integralwith supports 37 which are secured to'a carunderframe 38. Supports 37 are provided with downward extensions 37 "to which are connected the spring insulators.

' spirit and scope of my invention. v I claim-1' comprising a stationary support, 7 a -hori Zontally-disposedmember [secured to said 'A- motor mounting of my improved construction is simple and inexpensive to manufacture and can be easily attached in posi- ---tion, and the resilient members of the mot r support efiiciently absorb all vibration and the coil springs provide adjustable means for yieldingly holding the motor against dis placement and serve to prevent the transmission of vibration from stationary supports.

WhileI have shown anddescribedthe dif- "ferent forms of my invention, it is obvious that various changes in the construction and arrangement or" parts of my device may be made and substituted for those herein shown 'and described :without departing from the 1. A'mountin ,for motors and'the like .support and axially aligned inverted. shaped members pivotally suspended from 7 said horizontally'disposed member and havmg spaced de'pending'legs adapted to operatively'support therebetween a motor and thelike.
